Tank Level Sensors (RMA-FTL1-SEN & RMA-FTL2-SEN, RMA-WTL1-SEN & RMA-WTL2-SEN)

Dual Switch Point

The Tank Level Sensors have a high and low switch point with a differential in between.

While the float moves through the differential, its switch state remains unchanged until it

hits the high or low point, as shown below. You may adjust the height of this differential

by moving the weight closer to or further away from the float.

Install Your Tank Level Sensor

Do not use this sensor in hazardous (classified) locations or life safety applications.

Step 1: Mount your Tank Level Sensor.

You may use the attached polypropylene hanging clamp to hang your Tank Level Sensor.

The PVC-coated cable may be hung down a wall or in a corner of the tank—it does not

have to be suspended from the center. Allow a swing radius for the float that is equal to

the distance between the control weight and the face of the float.

Note that the height and depth (in feet and inches) at which the float switch changes state

depends on two factors:

•

the height at which the float is suspended in the tank by the hanging clamp

•

the distance between the float face and the control weight (which creates the

differential)

You may wish to experiment with different combinations to get the results you desire.

When considering the layout of your components, remember that the speaker wire cannot

withstand the same conditions as the PCV-coated cable attached to the float. Do not run

the speaker wire inside the tank or immerse it.

When the float switch

is on its way up, the

switch remains in the

same state until it

reaches the high point.

When the float switch

is on its way down,

the switch remains in

the same state until it

reaches the low point.
